To aZZfwhom z't concern.'

Be it known that I, EDWARD LUDnEN, a

citizen ofthe VUnited States, residing in Balta, inthe county of Pierce. and State of North Dakota, have invented certain new and useful Improvements in Machines for Packing Butter and Similar Material, of which the following is a specification.

The object of this invention is toprovide a machine for-.packing butter and similar substances which is simplein construction and which'will eiiiciently pack the-butter in such manner that it shall be uniformly` distributed and evenly pressed and leveled in its container.. A

When the butter is packed in tubs or iirkins which are of larger diameter at the top than at bottom and where rotary blades are employed to perform theV packingroperation the butter is made to rise at the'sides of the container more than in the middle portion thereof, thus producing a concave uneven surface at thetop vof .the mass .which is objectionablef Y Y According to my invention I provide means wherebyV the packers are made to rise and assume a level or horizontal position when the container is nearly full whereby a smooth and even condition is given tothe mass on its upper surface.

In the accompanying drawings, Figure 1 is a view partly in front elevation and partly in section of amachine for packing butter embodying my improvements. Fig. 2 shows a transverse section thereof on the line 2-2 of Fig. 1. Fig. 3 is a perspective view showing particularly how the packing blades are connected and supported.

A tubular casing A is held b v bolts a to a frame B which may be attached by brackets C or otherwise to a suitable support such as the ceiling of a cellar. A rotary hollow shaft D is mounted to rotate and to slideV hanging bracket h. It will be observed that the hollow shaft D is formed with a vertical slot d into which a lug e on thewheel E projects, so that the shaft is free to move vertically to a suicent extent relatively to I Specification of Letters Zlatent.Vv 14,191.6, Appnmmniea'iuiyz'z,1915.' serilNpAaiei.'

the toothed wheei.- a coiled spring i .within the casing A bears on top of the shaft D and tends -to force it downward. Itsupper end enters a cap ywhich is heldin I placejby screws J extendingV through nutsy' in the frame B. By adjusting' the screws the tencular packer. At its inner end each packer is hinged tothe lower end'ofA the tubular I shaft D by any suitable device such as that' indicated atV Ic, and the packers are all connected intermediate their inner and outer endsy to a "horizontally arranged ring L which is in turn connected to the lower endsv ofrodsM which extend through slots d Vin the shaft D and' at their upper ends connect with the lowerend of a vertical shaft N, which extends up through an opening fn, inv

the springcap z. The upper end of the rod N connects lwith va screw O extending through a nut o inthe frame B. The screwl VO is provided with a handiwheel: O by means of which the screw maybe operated to raise and lower the rod N and thus raise and lower the inner or uppery ends of the Vrods M which are pivotally connected with the rod N in the manner shown.

I In operation the packers are lowered int'o a receptacle X containing the material to be packed and the rod N is raised or lowered to the proper extent to hold the packers at the desired angle to allow them to be lowered to the lower portion ofthe con tainer which lower portion is of relatively small diameter. A rotary motion is then given to the tubular shaft D by the mechanism before described and the material is properly packed in the lowerportion ofn the container. More material such as butter is then Vadded and the packing operation is proceeded with. During the operation the material tends to rise higher at the sides of the container than in the middle portion thereof but this is resisted by the packers and the pressure is transferred to the central portion thereof which is forced upward against the force'of the spring I and finally assumes a substantially horizontal orlevel lcondition so as to give a smooth and level upper surface to the material. It' will be understood that when the packers are thus moved the upper ends of the rods M remain in the horizontal plane while moving about their pivotal connection with the rod N.

The form and number-f of the packers may be varied. I have shown a plurality of segmental members overlapping each other, but a less number may-be employed with spaces between; them. When overlapping packers are employed they should be so set that they will rise up over the butter or other material, force it under them and thus pack it.

f The machine is preferably' run `at about'v twenty revolutions per minute.

The opening-n 1n the spring cap z' is sufficiently large to allow the upper end nof the rod N'. to pass through it and `the screw is of suicient length to aord a wide range tically movable rotary shaftv to whichl theV packer is hinged at its inner end and with which it rotates, rods pivo'tally connected with the packer intermediate its 4inner and outer ends, a support towhich the upper ends of therods are pivoted, and a spring resisting the upward movement of said rotary shaft.
